WILLIAM E. THORNTON Signature of the surgeon and astronaut Envelope signed: "W. Thornton", 6½x3¾. Mission Specialist 3 William E. Thornton (1929-2021), a US Air Force flight surgeon, who had worked in ground support on the Skylab missions of the 1970s, flew into space himself on two shuttle missions: STS-8 (1983) and STS51B (1985), but his greatest contributions may come from his work on the ground. He studied muscle loss and mass in space flight, an important discovery in the development of long-duration space flights, and has since developed equipment and procedures to combat this. Fine condition.
